Drugs, Neurotransmitters, and Behavior

Volume 18 of the Handbook of Psychopharmacology represents the first of a series of volumes intended to bring earlier sections of the work up to date. Volumes 7, 8, and 9, published in 1977 and 1978, dealt with principles of behavior, drugs and neurotransmitters, and neuroanatomy. In subsequent volumes dedicated to these issues, a mixture of topics will be covered in a given volume, covering both advances in basic knowledge in these three areas of the subject and reviews of theoretical and meth odological issues deemed to be of particular relevance at present.
